Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

Advanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).

A Review on Current Challenges and Knowledge Gaps in Artificial Stone Silicosis

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background The global emergence of artificial stone (AS) silicosis represents a critical occupational health challenge. The aim of this systematic review is to provide an overview of the clinical, functional, radiological, and occupational characteristics of patients affected by AS silicosis at the time of diagnosis, and to identify current ...

Strain‐Tunable Photoluminescence From Ge Quantum Dots on Si Nanotips for CMOS‐Compatible Photonics

Advanced Physics Research, EarlyView.
This work studies strain in Ge quantum dots grown on Si nanotips using photoluminescence, X‐ray diffraction, and band structure calculations. It shows how emission changes with dot size, evaluates strain in the dot and substrate, and explains the role of direct and indirect transitions in the optical behavior.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Redescription of †Eobrasilia coutoi (Metatheria: Polydolopimorphia), a unique sclerocarpophagous metatherian from the Palaeogene of South America: Systematic affinities, and paleoecological and evolutionary implications

The Anatomical Record, EarlyView.
Abstract The ‘Palaeogene strata’ of the Itaboraí Basin (upper Paleocene‐lower Eocene), Southeastern Brazil, has preserved 29 genera and almost 50 species of metatherians (about 65% of its mammalian diversity). Among them, Eobrasilia coutoi Simpson, 1947 is the most enigmatic due to its quite fragmentary nature.
